Abstract

The utility model relates to a barrel type container with a build-in water storage bag. The shape and the volume of the water storage bag is similar to that of the barrel type container. A bag opening of the water storage bag can be extended out of the outside of the barrel type container opening and is sealed by a container cover. Gas exhaust bolts are arranged on one side of the container cover longitudinally and can be blocked or opened by a plunger piston. A breather bolt is arranged on the bottom side of the barrel type container and ventilating holes are arranged the breather bolt, and the ventilating holes can be sealed or opened by a piece of adhesive paper. The utility model has the advantages that air can not enter a water supply container under the states of discontinuity, succession or water supply waiting, and thus the pollution and deterioration of remanent liquid in the container caused by air can not be caused. The utility model is suitable for liquid conveying devices of water drinking machines and medical saline bottles.

Description

Negative pressure of vacuum water supply container device

A kind of negative pressure of vacuum water supply container device, the utility model are applicable to that the container that the various inversion types of no air-polluting supply water in the hygienic requirements installs use additional.

Scuttle-butt, the Beverage pail that the various inversion types of selling in the market or having enough to meet the need supply water all leans on entering of air to displace the interior liquid of container, this water supply method can cause the pollution of harmful substances in air to remaining liq in the container, high capacity particularly, the liquid in container of high hygienic requirements, the pollution, the spoilage problems that liquid are caused along with the prolongation air of used life are just more outstanding.Moreover the turnover container can cause the pollution problem of hiding again because of cleaning dirty.

The purpose of this utility model is exactly the case that will provide a kind of negative pressure of vacuum to supply water, also promptly be interrupted, continuously or wait not have in the air admission water supply container in each process of the state of supplying water, just can not causing air the pollution of remaining liq in the container, rotten.Moreover the replacing of water bag has avoided container because of the cleaning dirty pollution of hiding that causes again.

Scheme of the present utility model is to realize like this, in bucket formula container, place a water bag, the shape of water bag and volume are close with the shape and the volume of bucket formula container, the outside of extended barrel of formula vessel port of the sack of water bag, but with the sack of this container cover cap seal water bag.Side in container cover is provided with blow-cook, is provided with breather plug in a side of bucket formula container bottom.Blow-cook be along container cover vertically establish a small cylindrical opening, this small cylindrical opening can stop up or open with a plunger.Breather plug is to open a circular hole in a side of bucket formula container bottom, and this circular hole is opened a ventilation circular hole with a breather plug cap seal, the middle part of this breather plug one end, and two ventilation circular holes, this three holes intercommunication are opened in the both sides of the other end.

The utility model has the advantages that and do to be interrupted, continuously or wait not have in the air admission water supply container in each process of the state of supplying water, can not cause air the pollution of remaining liq in the container, rotten.Moreover each back of using has avoided container because of the cleaning dirty pollution of hiding that causes again to the replacing of water bag.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the utility model cross-sectional schematic.

Accompanying drawing 2 is cutaway views of container cover (2).

Accompanying drawing 3 is amplification views of breather plug (6).

Describe architectural feature of the present utility model and embodiment in detail below in conjunction with accompanying drawing, see also accompanying drawing 1, water bag (5) among the figure in the negative pressure of vacuum water supply container device is installed in barrel formula container (1), as seen both shapes and volume are close, outside the mouth of extended barrel of formula container of the sack of water bag (5) (1), used vessel lid (2) is locked in a container cover (2) and barrel contact site of formula container (1) mouth with the sack of water bag (5).When in water bag (5), pouring water, unnecessary air discharges by the blow-cook (4) that is installed in the container cover (2) in the water bag (5), stop up blow-cook (4) with a plunger after treating to fill in the water bag (5) water, make water blocking (3) stop up water inlet simultaneously, and, make the water in the water bag (5) between carrying and storage period, all be in vacuum state with the breather plug (6) of bucket formula container (1) bottom outside viscosity gummed paper cap seal.In case when being inverted bucket formula container (1) on the external water dispenser of back insertion, water blocking (3) is backed down by the mozzle in the external water dispenser immediately, the viscosity gummed paper of removing on the breather plug (6) makes breather plug (6) open-minded, and the water in the water bag (5) promptly is in the water supply state for the treatment of of vacuum.When opening external water dispenser valve work interruption or continuous water supply, because of breather plug (6) is in opening state, make bar pressure pass through the contact site that breather plug (6) directly is added to barrel formula container (1) and water bag (5), so the top of the water bag (5) in the bucket formula container (1) is in barotropic state.Water in the water bag (5) produces suction function because of the high low head of liquid level, make the mozzle of the interior hydraulic pressure of water bag (5) to water dispenser, outwards flow out through the water dispenser valve, institute just can not cause that remaining liq is subjected to the pollution of air so that whole water supply process is in no air-polluting negative pressure of vacuum water supply state all the time yet.

See also accompanying drawing 2,3, the blow-cook (4) of container cover (2) one sides in the accompanying drawing 2 be container cover (2) vertically establish a small cylindrical opening, this small cylindrical opening can inject with a plunger and stop up.Water blocking (3) is to be backed down automatically by the mozzle in the water dispenser when bucket formula container (1) is inverted the external water dispenser of reeve; Breather plug in the accompanying drawing 3 (6) is that cap seal is in the circular hole that bucket formula container (1) bottom is offered, the middle part of breather plug (6) one ends has a ventilation circular hole (8), the both sides of the other end have ventilation circular hole (9), (10), these (8), (9), (10) three hole intercommunications, in fill water or carrying way, with a viscosity gummed paper cap seal on the breather plug outside the bucket formula container bottom.

The utility model can be applicable to medical tuck saline bottle, medical tuck saline bottle also is that saline bottle is inverted, on the lid of bottleneck, insert water conservancy diversion syringe needle and air guide syringe needle, the soup that just displaces in the saline bottle that enters by air, make soup inject human body, be subjected to aerial contamination, can in saline bottle, put into a liquid storage bag for avoiding soup, establish a breather plug in the bottom of bottle, in the feed flow process, do not have in the air admission saline bottle.
